Handheld Loop Resistance Tester

The SMRL10S handheld loop resistance tester is a high-precision, digital switch testing instrument meticulously developed by our company based on IEC standards and the latest power implementation standard of the People's Republic of China, DL/T845.4-2004, leveraging our technological advantages. This instrument employs high-frequency, high-power constant current switching power supply technology, capable of measuring micro-ohm level contact resistance. It is widely applicable to measuring the contact resistance, loop resistance, and contact resistance of various switches and electrical appliances, as well as cables, wires, and welds. The instrument provides accurate measurement data and stable performance, meeting the requirements of power supply departments for on-site high-voltage switch maintenance and high-voltage switch factory loop resistance testing. The output current and measured resistance are simultaneously displayed on a 7-inch high-brightness touchscreen color LCD. Measurement results can be output as voltage or stored on a USB flash drive, with data retrieval available even after power failure.

1. Features multiple protection functions including back EMF impact, wire breakage during testing, power outage, and power supply overheating protection, reliably protecting the instrument from back EMF impacts and providing a simultaneous audible alarm.

2. Intelligent power management technology ensures the instrument always operates at low power, effectively saving energy and reducing heat generation.

3. The instrument supports free switching between Chinese and English, features high output voltage, and a wide measurement range.

4. The test current comes from a high-precision, high-current constant power supply, requiring no manual adjustment and ensuring rapid and accurate testing.

5. Utilizing a four-terminal wiring method, it effectively eliminates the influence of test lead resistance on the test results.

6. A 7-inch high-brightness touchscreen color LCD provides clear display even in strong light, supports full touchscreen operation, and allows free switching between Chinese and English.

7. The instrument includes a built-in perpetual calendar clock and power-off memory, capable of storing 1000 sets of test data for easy access.
